Extract

The problems of regeneration, and those relating to the production of adventitious structures in general, have not been extensively studied in the Lycopodiales, although the production of adventitious structures, some of them regenerative in nature, has been recorded for all four of the living genera. Selaginella has been examined more thoroughly in this respect than the other three genera. Adventitious roots have been induced to develop from decapitated rhizophores and from isolated lengths of stem; the production of adventitious shoots from rhizophore rudiments has also been obtained by experimental methods. Goebel (7, p. 1220) has described the development of adventitious buds on the leaf bases of Isoetes lacustris, and Osborn (12) has described interesting regenerative developments from detached leaves of Phylloglossum Drummondii. A number of examples of regeneration in various species of Lycopodium has been recorded. Goebel (5, p. 46) states that the first leaves of embryo plants of L. inundatum may produce adventitious shoots. The same writer (6, p. 83) has recorded, but not described in detail, the development of adventitious outgrowths from the decapitated shoots of young plants of L. Selago and from isolated bulbil leaves of the same species. The development of adventitious buds on isolated roots and leaves of L. ramulosum has been described by Holloway (8).
